Official title: Multicentric Case Series of Uniportal Endoscopic Posterior Cervical Decompression for Cervical Spinal Stenosis
Run by TecSalud Investigación Clínica · NCT06886802 · Data updated 2026-11-12
This study will try a minimally invasive single‑incision endoscopic posterior decompression to relieve pain, numbness, and weakness in adults with cervical spinal stenosis who have not improved after at least three months of conservative care.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults with cervical canal stenosis grade I–III (Kang scale) who have radicular or myelopathic symptoms, have failed at least three months of conservative treatment, and have not had prior surgery at the treated levels.
✕Probably not a fit
Patients with cervical instability, disc herniation at the index level, medullary T2 hyperintensity, prior surgery at the target levels, active infection, rheumatologic disease, or congenital spinal malformations are unlikely to benefit from this approach.

What this trial studies
This multicenter prospective case series will enroll 50 patients across three Mexican institutions to receive posterior uniportal endoscopic cervical decompression. The procedure uses a single small incision and endoscopic instruments to target and decompress neural structures while minimizing muscle and tissue disruption. Primary outcomes include changes in neurological deficits and disability related to cervical pain, with secondary measures of hospital stay, operative time, blood loss, and postoperative complications. The study is planned over 24 months with an initial 12‑month recruitment period and standardized data collection at participating centers.
Why it matters
Potential benefit: If successful, the procedure could reduce tissue damage, postoperative pain, and hospital stay while improving neurological symptoms compared with more invasive open approaches.
How similar studies have gone: Minimally invasive endoscopic decompression techniques have shown promising results in small case series, but the uniportal posterior cervical approach remains relatively novel with limited high‑quality comparative evidence.
